Display device
A display device is capable of preventing electro-static discharge by attaching a driving integrated circuit cover to a driving integrated circuit and a flexible printed circuit board, the display device including a display panel including a display area and a non-display area, a driving integrated circuit for providing signals, data, and voltages to the display area, a flexible printed circuit board coupled to the driving integrated circuit, and including an open ground portion at one side of the flexible printed circuit board, and an integrated circuit cover portion overlapping the driving integrated circuit and at least a portion of the flexible printed circuit board, and including a cut portion at an area corresponding to the open ground portion.
1. A display device comprising:
a display panel comprising a display area and a non-display area;
a driving integrated circuit for providing signals, data, and voltages to the display area;
a flexible printed circuit board coupled to the driving integrated circuit, and comprising an open ground portion at one side of the flexible printed circuit board; and
an integrated circuit cover portion overlapping the driving integrated circuit and at least a portion of the flexible printed circuit board, and comprising a cut portion at an area corresponding to the open ground portion.
2. The display device of claim 1 , wherein the cut portion comprises at least two attachment pieces that define a slit or opening.
3. The display device of claim 2 , wherein at least one of the attachment pieces is bent and contacts the open ground portion.
4. The display device of claim 3 , further comprising an adhesive resin between at least one of the attachment pieces and the open ground portion.
5. The display device of claim 3 , wherein the slit or opening exposes a portion of the open ground portion in a plan view.
6. The display device of claim 2 , wherein the slit or opening has a different width in a plan view according to a relation to a position of at least one of the attachment pieces.
7. The display device of claim 2 , wherein the slit or opening has a greater width toward a center portion of the open ground portion in a plan view.
8. The display device of claim 7 , wherein at least one of the attachment pieces has a pointed end.
9. The display device of claim 2 , wherein the slit or opening has an X-like shape or a cross-shape.
10. The display device of claim 2 , wherein the slit or opening extends substantially parallel to one side of the cut portion.
11. The display device of claim 10 , wherein the slit or opening comprises a first slit or opening, and a second slit or opening that is parallel to the first slit or opening.
12. The display device of claim 2 , wherein the slit or opening extends in a diagonal direction of the cut portion.
13. The display device of claim 1 , wherein the integrated circuit cover portion does not overlap elements at the flexible printed circuit board.
14. The display device of claim 1 , wherein the integrated circuit cover portion overlaps elements at the flexible printed circuit board.
15. The display device of claim 1 , further comprising a non-conductive tape between the integrated circuit cover portion and the driving integrated circuit.
16. The display device of claim 15 , wherein the non-conductive tape comprises an adhesive resin at opposite sides thereof.
17. The display device of claim 1 , wherein the driving integrated circuit is at the non-display area of the display panel.
18. A display device comprising:
a display panel comprising a display area and a non-display area;
a driving integrated circuit for providing signals, data, and voltages to the display area;
a flexible printed circuit board comprising a plurality of wiring layers that are coupled to the driving integrated circuit, and a cover layer that at least partially covers the plurality of wiring layers, and that defines a plurality of opening depressions exposing at least a portion of the plurality of wiring layers, at least one of the plurality of opening depressions comprising an open ground portion; and
an integrated circuit cover portion overlapping the driving integrated circuit and at least a portion of the flexible printed circuit board, and comprising a cut portion that is at an area corresponding to the open ground portion and that defines at least one slit or opening.
19. The display device of claim 18 , wherein the cut portion comprises an attachment piece that is bent at the cover layer and that contacts the open ground portion.
20. The display device of claim 19 , further comprising an adhesive resin between the attachment piece and the open ground portion.
21. The display device of claim 19 , wherein the slit or opening has a different width according to a relation to a position of the attachment piece.
22. The display device of claim 19 , wherein the slit or opening has a greater width toward a center portion of the open ground portion.
23. The display device of claim 18 , wherein the slit or opening exposes a portion of the open ground portion of the flexible printed circuit board.
24. The display device of claim 18 , further comprising a non-conductive tape between the integrated circuit cover portion and the driving integrated circuit.
25. The display device of claim 18 , wherein the flexible printed circuit board comprises an element at another of the plurality of opening depressions.
